Embodiment
Spiral reinforced hose A of the present invention, shown in Fig. 1～3, for example, in the inside that is configured as flexible pipe body 1 cylindraceous by soft thermoplastic synthetic resins such as for example vinyl chloride resins, will by the fine line diameter that hard resins such as polyester resin or nylon resin are configured as coil spring shape extend monofilament 2 under the state of many of flexible pipe axially-aligned equidistantly to be wound in helical.
Below, various embodiments of the present invention are described with reference to the accompanying drawings.
Above-mentioned flexible pipe body 1, shown in the public strictly according to the facts clear 63-46783 communique, be to constitute by internal layer and skin, and can adopt and between these internal layers and skin, sandwich and twine two and extend monofilament 2,2 and as spiral reinforced hose A, perhaps adopt shown in the public clear 50-31198 communique of spy, by well-known flexible pipe autofrettage, will have two shoestring that extend monofilament 2,2 and be wound in helical, and its approximal surface is bonding mutually and as spiral reinforced hose A.
Particularly, shown in the public strictly according to the facts clear 63-46783 communique, by the stacked method of making flexible pipe, at first, extrude internal layer from extruder continuously with fusion or semi-molten state, and under the state that extends monofilament 2 on this internal layer towards two of flexible pipe axially-aligned, be wound in helical, then, the stacked in the above skin of extruding continuously with fusion or semi-molten state from extruder sandwiches and twines two thus and extends monofilament 2,2 and it is integral between these internal layers and skin.
Shown in the public clear 50-31198 communique of spy, by the bonding method of making flexible pipe of spiral, at first, extrude continuously with the shoestring of soft synthetic resin covering around two extension monofilament 2,2 of flexible pipe axially-aligned with fusion or semi-molten state from extruder, then, this shoestring is wrapped in helical on the outer surface of the screw axis that is supported with the single armed state, simultaneously that the approximal surface of this shoestring is bonding mutually, thus be configured as tubulose and make its becoming one.
In addition, in the exemplary plot, by being set at 3: 7 to the size ratio of interval S between two extension monofilament 2,2 of flexible pipe axially-aligned and the distance P between the axially adjacent spiral of flexible pipe, make distance P between spiral greater than two intervals of extending monofilament 2,2, promptly greater than between the two interval S, thus flexible pipe axially on the local formation no core 1a that can have an X-rayed.These extend interval S between monofilament 2,2 and the size ratio of the distance P between spiral is not limited only to 3: 7, though not shownly also can change, as 2: 8 or 4: 6 etc.
Secondly, the action effect about this spiral reinforced hose A is described.
Owing to extend monofilament 2,2 with two of equidistantly having twined to the flexible pipe axially-aligned to flexible pipe axial screw shape, so these interval S of extending between the monofilament 2,2 narrow down, even line separately directly attenuates, the withstand voltage properties of this part can not reduce yet, and can access and twine flexible pipe that a thick line directly extends monofilament about equally or its above withstand voltage properties.
Thus, use the extension monofilament of fine line diameter, correspondingly can reduce the pipe thickness size T of flexible pipe body 1, thereby can realize the lightweight of spiral reinforced hose A, and improve pliability.
In the present embodiment, because each sectional shape that extends monofilament 2 forms the flat pattern of the wide size W of its core greater than the thick dimension D of core, so not only compression area becomes big, the also attenuation of size T of the pipe thickness of flexible pipe body 1 is simultaneously disposed flexible pipe body 1 difficult expansion of respectively extending monofilament 2 positions thereby make.
Thus, when improving withstand voltage properties, further reduce the size T of flexible pipe pipe thickness, and can improve the flatness of outside in the flexible pipe.
And, as shown in the figure,, then seldom cause harmful effect such as break to covering this extensions monofilament 2 flexible pipe body 1 on every side if each sectional shape that extends monofilament 2 is formed ellipse.
In addition, because by axially going up distance P between adjacent spiral to flexible pipe greater than the interval S between a plurality of extension monofilament 2 of flexible pipe axially-aligned, the no core 1a that local formation can be had an X-rayed flexible pipe is axial, so be not subjected to the obstruction of flat extension monofilament 2, can see fluid that flows through in the flexible pipe etc. from no core 1a.
Above-mentioned identification line 3, for example, the thermoplastic resin that vinyl chloride resin or polyethylene etc. and flexible pipe body 1 homogeneity is not homochromy is extruded and is formed on the flexible pipe outer surface 1b, both are integral, perhaps will with the not homochromy thermoplastic resin system band hot press of flexible pipe body 1 homogeneity on flexible pipe outer surface 1b, both are integral.
In exemplary plot, though only form an identification line 3 that axially is straight line shape extension to flexible pipe, it is a kind of that but its number, thickness or color are not limited to, for example can dispose the color difference but many identical identification lines 3 of width, also can dispose the different a plurality of identification lines 3 of width, perhaps roughly become with one side is buried to establish identification line 3 with flexible pipe outer surface 1b, and as required can be as shown in the figure on identification line 3 double exposure literal such as Business Name or diameter dimension for example.
Therefore, spiral reinforced hose shown in Figure 2, except accessing the action effect identical with the foregoing description 1, if by making the identification line 3 that is different from flexible pipe body 1 color connect the two end part of flexible pipe to the mode difference pipe arrangement that axially is straight line, just can realize not having the flexible pipe pipe arrangement of the best of distortion, simultaneously, even pipe arrangement is shorter, because identification line 3 extends to axially being a straight line shape, so also be easy to distinguish with other pipe arrangement, and, can obtain the different multiple flexible pipe of outward appearance to discern the different colours of line 3.
Therefore, not only can prevent the breakage that flexible pipe is caused by distortion, and can be by identification line 3 by use or type identification flexible pipe.
Embodiment 3
Present embodiment 3, as shown in Figure 3, except changing two colors of extending monofilament 2,2 to above-mentioned flexible pipe axially-aligned, and outside the structure that can have an X-rayed these colors of extending monofilament 2,2 from the outside of flexible pipe body 1 and above-mentioned embodiment shown in Figure 11 were different, other structure was identical with embodiment 1 shown in Figure 1.
For example, with a side extension monofilament 2 outer surface forms white at least the time, preferably the outer surface at least of the opposing party's extension monofilament 2 is formed the combination that green, redness or blueness etc. beyond the white can clearly be distinguished.
And, in illustrative example, to be made as 0 and connect to two of axially-aligned interval S of extending between the monofilament 2,2, simultaneously both sectional shapes of butt state are formed ellipse etc., and make it be the flat pattern of the wide size W of core greater than the thick dimension D of core, but be not limited thereto, embodiment 1 as shown in Figure 1 is such, also can open in 2,2 minutes, the dimension scale of between the two interval S and the distance P between spiral is made as for example 2: 8,3: 7 or 4: 6 etc. extending monofilament.
In addition, embodiment as shown in Figure 2 also can be provided with the identification line 3 that extends to axial direction on the outer surface 1b of flexible pipe body 1.
Therefore, spiral reinforced hose shown in Figure 3, except accessing the action effect identical with the foregoing description 1, owing to changed two colors of extending monofilament 2,2 to the flexible pipe axially-aligned, and form flexible pipe body 1, so can obtain the different multiple flexible pipe of outward appearance by the different colours that extends monofilament 2,2 by the material that can have an X-rayed.
Therefore, can discern flexible pipe easily by use or type by the color of extending monofilament 2,2.
And in the foregoing description 1～3, though by the transparent or translucent material forming flexible pipe body 1 of having an X-rayed inside, be not limited to this, flexible pipe body 1 also can be formed by opaque material.
And, extend to two of axially-aligned under the state of monofilament 2 equidistantly to be wound in spiral helicine example though enumerated in the inside of flexible pipe body 1, but be not limited to this, also can to the flexible pipe axially-aligned more than or equal to the state of 3 extension monofilament 2 under equidistantly to be wound in helical.
In this case, can use the extension monofilament that corresponding ground wire directly becomes thinner owing to increased the bar number of extension monofilament 2.
In addition, though each sectional shape that extends monofilament 2 is formed ellipse etc., and make it be the flat pattern of the wide size W of core greater than the thick dimension D of core, but be not limited to this, sectional shape also can be the flat pattern beyond the not shown ellipse, perhaps also can not be flat pattern but cross section circle.
